Compressor Control Valve Assembly: Description and Operation

A/C Compressor Regulator Valve N280

The regulator valve is installed in the A/C compressor. It is activated by the A/C Control Head E87 or the Climatronic Control Module J255. Pressure on the low pressure side is influenced via the regulator valve and thus regulates the temperature in the evaporator.

NOTE: A/C Compressor Regulator Valve N280 is a structural component of the A/C compressor and cannot be replaced separately.
